   HPA-3U plus (USB) 24bit/192kHz + DSD Headphone Amplifier

The M-STAGE HPA-3U + is a biggest evolution since the M-Stage series headphone amplifier came out, the new appearance, the new circuit design and radical performance improvement to make it all difference.

The M-STAGE HPA-3U + full-band of THD + N less than 0.0003%, SNR up to -112dB, bandwidth not less than 150k at -3dB gain, 0.2Ω ultra low output impedance, three gain level options to fit for the different impedance and sensitivity headphone, all of these excellence performance improvements to be born the brand new HPA-3U!


The M-STAGE HPA-3U + is the most stable XMOS U series USB controller on the new USB module, support 24 bit/192kHz sample rate PCM signal playback, DOP mode DSD playback capacity and DSD ASIO Native playback, the biggest bright spot is that can be played with your iOS and the most Android devices.

The M-STAGE HPA-3U + excellent structural design to quickly dissipate the heat of power transistors via the shell, to ensured the stability of the work; full symmetric circuit layout makes two channels audio have the isometric path; driver stage use the precision constant current source and establish stable working point; Parallel output of the output stage can effectively reduce the output impedance, and improved driving capability, extended dynamic range.

The M-STAGE HPA-3U + uses an Alps 27 series volume potentiometer, Wima and Nichicon audio gradecapacitors, Noratel toroidal transformer, precision non-inductive resistance, each carefully selected components make HPA-3U not only presents the perfect sound, but also a more stable and reliable.
